Embodiment Construction

[0009] 1. In the early stage of grafting, dig a 30cm wide × 40cm deep annular ditch 1m away from the root of the mango tree, cut off the root system to reduce the transportation of water and nutrients, and achieve the balance of water and nutrients after grafting.

[0010] 2. Cut the big mango tree 1m away from the ground at one time, and graft it by cutting. The depth of the incision groove to the length of the cambium is 4-6cm, the length of the scion is 6-9cm, and the length of the top is 2-3cm. Select 2-3 strong buds at the back end and cut them into a 45° bevel, slide to the cambium of the incision, and then place the scion And the whole rootstock is bound firmly.

[0011] 3. Spray the scion and pile with carbendazim 3 days after grafting, and paint the tree body with 5% salt solution with quicklime and 7 days after grafting.

[0012] 4. When the newly grafted graft grows to 18cm, top off the heart in time to promote branching and quickly form a crown.

Abstract

The invention provides a high-pile variety changing method for aged mango trees, which is characterized in that: 1. in an earlier stage of grafting, an annular ditch which is 30 centimeters wide and 40 centimeters deep is dug on the periphery which is 1 to 1.5 meters away from the root of a mango tree, so as to cut off a root system, reduce the transport of moisture and nutrients and achieve the balance between moisture and nutrients after grafting; 2. a position on the mango tree, which is 0.8 to 1 meter away from the ground, is integrally cut once and for all and is grafted by a cut grafting method; 3. a scion and a pile body are sprayed with carbendazim 2 to 5 days after grafting, and a tree body is brushed with quicklime plus 4-6 mass percent table salt liquid after 7 to 9 days of grafting; and 4. when a new grafted survived treetop grows to 15 to 20 centimeters, the new tree top is pinched in time so as to promote branching and form a tree crown rapidly. The method ensures that the survival rate of grafting and changing the variety of the aged mango trees reaches more than 93 percent; a new tree crown in the second year after grafting can reach more than 2 meters; and single plant can bear more than 8 kilograms of fruits on the average. The method has the advantages of shortening the reformation period of aged mango orchards and improving the economic benefit of the orchards.

Description

technical field [0001] The invention relates to a method for replanting mango trees with high piles, in particular to a method for replanting old mango trees with high piles. Background technique [0002] Mango is a tree species with a long lifespan, but it has been planted for many years, and there are problems such as species degradation and low yield. Using high-grafting methods, replacing it with high-quality new varieties, and improving the variety of mango orchards is the adjustment and optimization of mango varieties. structure, a fast and effective way to improve the economic benefits of mango. At present, for the transformation of old mango trees, one adopts the method of sawing off the main side branches, taking out new shoots at the saw kerf and grafting on the new shoots after they are mature, but there is a problem of long transformation period; The method of grafting, but there is the problem that the canopy cannot be dwarfed. Contents of the invention [0...
